Is the audio coming from the TV's internal speakers, or from an
external sound system? In the 169 series chassis, if the power supply
caps or secondary rectifier are bad, or if the high voltage splitter
has shorted inside, the set will not run and there will be no picture
or sound from the TV. If the picture is completely black but the TV
still has audio, press the menu button and see if the menu comes up on
the screen. If the menu is there, check your cables on the back of the
TV. If you are using a cable or satellite box, the box could be bad or
the video wire could be bad or loose. If you do not get the on-screen
menu, then I would guess that the solder joint next to the flyback
transformer that sends filament (heater) voltage up to the picture
tubes has cracked, or the low value resistor in the heater circuit has
opened up. If that is the case, have the set serviced by a qualified
tech familiar with the 169 series chassis.
if the TV dose not detect a viable video signal it will mute the sound and blank the video there is a preset minimum level that enables the audio and video, insure that the video source is of good quality and the cable you are using is good, if it is than you may have a problem in the video processing circuits of your TV, the good menu screens indicate this may be the fault,,, Good luck
Does the menu come up if you press the menu button? If not then there is a few things that can cause this problem. most likely is a fluid leak, to check for fluids i would take the front off the bottom of the set and look in with a flashlight and see if you see any liquid on the boards or corrosion of any type. let me know what you find.
I can take perfect pictures indisde a building, but taking a picture outside, I can see the item but if I take the picture and looking at the picture the screen turns blank, seems to me that there is to much light exposure.
